They include the introduction of a 24-hour post-booking “grace” period, during which passengers can correct minor errors such as spelling mistakes free of charge.

Passengers are also now allowed on board with a second “small” carry-on bag, such as a “small ladies handbag or [a] small airport shopping bag”, while the airline's boarding pass re-issue fee has been cut from £70 to £15.

On all flights that operate before 8am, or after 9pm, public announcements are now restricted to essential safety messages and cabin lights dimmed “so that any customers who wish to snooze, can comfortably do so.”

Further changes are scheduled for next year. On January 5, the charge for checking luggage at the airport (rather than online) will fall from £60 to £30 per bag, and on February 1 it will introduce fully allocated seating on all flights.
